    摘要： An amplifier device, such as an operational amplifier device or unity gain buffer, may include a first input terminal, an inverting input terminal, a non-inverting input terminal, a reference voltage supply terminal, a negative voltage supply terminal, and an output terminal. The amplifier device may include one or more cascode arrangements, such as a first cascode arrangement coupled between the negative voltage supply terminal and the output terminal. A first transistor of the first cascode stage may be configured to receive a variable bias voltage at its gate terminal. A second transistor of the first cascode stage may be configured to receive a fixed bias voltage at its gate terminal. The variable bias voltage may correspond to a first input voltage supplied at the first input terminal.

    摘要： Embodiments of RF amplifiers and packaged RF amplifier devices each include an amplification path with a transistor die, and an output-side impedance matching circuit having a T-match circuit topology. The output-side impedance matching circuit includes a first inductive element connected between the transistor output terminal and a quasi RF cold point node, a second inductive element connected between the quasi RF cold point node and an output of the amplification path, and a first capacitance connected between the quasi RF cold point node and a ground reference node. The RF amplifiers and devices also include a baseband termination circuit connected to the quasi RF cold point node, which includes a third inductive element, a resistor, and a second capacitance in series between the quasi RF cold point node and the ground reference node and a third capacitance between a baseband termination circuit node and the ground reference node.

    摘要： Embodiments of a method and an apparatus for multi-link communications are disclosed. In an embodiment, a method for multi-link communications involves announcing, by a non-access point (non-AP) multi-link device (MLD) to an access point (AP) MLD, a frame exchange restriction in an enhanced multi-link operation, receiving, by the AP MLD from the non-AP MLD, the frame exchange restriction, and transmitting, by the AP MLD to the non-AP MLD, an initial frame according to the frame exchange restriction.

    摘要： A GPIO includes a transmitter having an output stage connected to the I/O pad and adapted to supply transmit data to an I/O pad in response to output data generated by a low voltage core logic operating within a functional voltage range for transmit operations; a receiver adapted to supply receive data to the low voltage core logic operating within the functional voltage range in response to input data received at the I/O pad for receive operations; a VLV transmitter adapted to supply VLV transmit data to the output stage of the transmitter and not directly to the I/O pad in response to output test data generated by the low voltage core logic; and a VLV receiver adapted to supply VLV receive data to the low voltage core logic operating within a low core supply voltage range in response to input data received from the output stage of the transmitter.
